U have to give us the passage also so I don’t think anyone can help unless they’ve done it before
The prepositional phrase in this sentence is c. "to your sentence structure", because it is postmodifying an infinitive phrase (to bring complexity), which has the same value, in this case, as a noun phrase. Besides it is composed by a preposition (to) and a noun phrase (your sentence structure).
Option a. is a verb phrase as well as option b. In the same way, letter d. is not a prepositional phrase as it is an adjective phrase used in the comparative form.
C. Point of view because it is who tells the story and how is it told
I believe its B racial hatred
Answer: The verb is: "should have been" .
